Bridesmaids

I seriously don't know what I'd do without you ladies on here! Okay so I have a questions about bridesmaids. Is it normal to do a lot of wedding planning by yourself without much help from your bridesmaids? Even with reaching out to them. FH are a self pay couple and I am doing the planning but I am feeling really alone. I have 6 bridesmaids and my wedding is 10/10/2020. I have one in particular who was super excited and really wanted to be a bridesmaid, she's the FH sister who is in her 30's. And now it's coming down to really planning and she is saying she isn't getting texts emails. I guess what I wanna know is if it's something I shouldn't have much expectation for as far as them helping?
